Passing Gas

The other day, I was chasing down the problem on a slow leaking tire. In the era of tubeless tires with Cushcore, flat fixing, while rare, isn’t trivial. It’s nice when a puncture is obvious but often now, it isn’t. So we need to go to the dunk tank. Until recently this was my kitchen … Read more Passing Gas

Filigree

Using a fiber laser to mark the outside of a cylinder is relatively common. The EZcad software breaks a graphic into a polygonal cylinder and marks the part while indexing a stepper motor axis. It’s crude but works well enough for most work. The precision and expertise of the user will produce differing results, better … Read more Filigree

Laser Marking

More on the new frame fixture details… I started on this path when the employer of a friend took delivery of a fiber laser for marking parts. I would have been able to get some limited access to this but, sadly, COVID-19 ate the company up and that opportunity disappeared along with my friends job. … Read more Laser Marking

The finish line.

Advice for the aspiring designer; Have lots of patience, keep working hard, don’t ever stop! I’m currently working on producing a new fixture for making my bicycle frames (a mandrel bender also but that is another story). I need a tool that will work better than what I have been using for modern geometries, mopeds … Read more The finish line.

PVD/RAD Refined

Back in November 2019, I posted  a stream of consciousness, ending in an enlightening concept: PVD/RAD. It looked promising even in that primordial state. The problem with that post is that it was confusing and left folks with more questions about the process than the answers it could have. Six months later, I’m still excited … Read more PVD/RAD Refined

Sonofabitch

Today is my day to eat some crow. Attentive readers will know of my work on brake caliper mount locations and a tool for attaching flat mount caliper bosses in the correct location. I’ve been pretty proud of this work. It cleans up a big mess. Devin Bodony of Lichen Precision, a machinist bro that … Read more Sonofabitch

Manfrotto Mini-Me

More photo stuff… With Canon’s release (Fucking finally) of a DSLR driver for webcam use in the age of COVID-19, we have entirely new practical uses for photo gear. Quality webcam use has become very important to looking professional. You should put some thought into this. Good lighting is important. Some headphones. A decent background. … Read more Manfrotto Mini-Me

It is difficult to represent the seller in the paid exchange of sexual services

That’s right. Pimpin’ ain’t easy. I try to look very closely at all aspects of my riding. That’s not restricted to my bike or the trails that I’m on but also what I’m wearing. Anything can be optimized! What do you need? Make that happen. I’ve talked in the past about the need to cut … Read more It is difficult to represent the seller in the paid exchange of sexual services

Flop

This came up in a discussion the other day. I figured that I’d bring it up here as it is current in what I’ve done in a recent design. I’ve been working with my klunker platform enthusiastically and have just produced the Supermarine Spitfire which was building on the Sopwith Camel. It makes use of … Read more Flop

New carbon

Just touching base on what has been keeping me busy recently. After the Supermarine Spitfire crash, I took a deeper look at the materials that I use in my handlebars. A greater safety factor was needed at the cost of a little bit of flex. Some of these bars have been in service for next … Read more New carbon

Dunkirk

Gambling is an art with a vicious side to it. We bet on black and by magic, we get black…over and over. We get cocky. We think we know what we are doing. Then, up comes red and we are busted again. The gambler always loses. Dunkirk. The first ride on the PVD Supermarine Spitfire … Read more Dunkirk
